So, is the correct term “sextortion”?

We talk a lot about blackmail scams, webcam blackmail and sextortion, and most people assume it’s the same thing.  But is it?  I’m really not sure if I’m honest.  Sextortion can be for money or other things, and that’s the issue.  It’s not just about the money.  Some do it for the thrill, some do it to get more from the victim, some do it for control.  The media likes the term.  Myself, I think that “webcam blackmail” better explains what it is.  What to others think?
